Hi Dominic,

Curval() only work if you are using buffering. Refresh() is used to refresh a view that will generally be either Row or Table buffered. The two functions you refer to usually operate on buffered data and you specify that your table is not buffered. To test for conflicts, maybe you should consider buffering your table.
